EMFStore has a abstract persistence layer, the default implementation is
XMI. 2 years ago, we had an implementation for DB based on Teneo. We
discovered, that due to the kind of read/write operations on the server
XMI was faster than the DB implementation. The server mostyl stores data
and quite seldom reads it again, mainly only if you access the history.
As a disadvantage, a DB back-end makes the model migration much more
complicated. If DB storage is required, that is definitly possible to
implement. Could you open a bug report in this case, to discuss this?
